Tim Northover 3e84ad28d4 ISelDAG: spot chain cycles involving MachineNodes ... Previously, the DAGISel function WalkChainUsers was spotting that it had entered already-selected territory by whether a node was a MachineNode (amongst other things). Since it's fairly common practice to insert MachineNodes during ISelLowering, this was not the correct check. Looking around, it seems that other nodes get their NodeId set to -1 upon selection, so this makes sure the same thing happens to all MachineNodes and uses that characteristic to determine whether we should stop looking for a loop during selection. This should fix PR15840. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@191165 91177308-0d34-0410-b5e6-96231b3b80d8		2013-09-22 08:21:56 +00:00
